[Intel-xe] [PATCH 2/2] drm/xe/uapi: Remove useless max_page_size

[Rodrigo Vivi]

The min_page_size is useful information to ensure alignment and it is
an API actually in use. However max_page_size doesn't bring any useful
information to the userspace hence being not used at all.

So, let's remove and only bring it back if that ever gets used.
